-# Security Advisory: High Severity Vulnerabilities - May 30, 2026
-
-This advisory addresses 3 HIGH severity vulnerabilities identified by Vanta security scans.
-
-## Summary
-
-| CVE | Package | Severity | CVSS | Status | Fixed Version |
-|-----|---------|----------|------|--------|---------------|
-| CVE-2026-29063 | immutable | HIGH | 9.8 | OVERDUE | 5.1.5 |
-| CVE-2025-58754 | axios | HIGH | 8.2 | OVERDUE | 1.12.0 |
-| CVE-2026-32460 | langsmith | HIGH | 7.1 | Due Jun 12 | 0.6.0 |
-
-## Vulnerability Details
-
-### 1. CVE-2026-29063: Prototype Pollution in immutable
-
-**Location:** Transitive dependency in `openmemory/ui`  
-**Current Version:** 5.1.1  
-**Required Version:** >= 5.1.5
-
-**Impact:**
-- Prototype pollution via `mergeDeep()`, `mergeDeepWith()`, `merge()`, `Map.toJS()`, `Map.toObject()`
-- Privilege escalation through `__proto__` injection
-- Security check bypass
-
-**Remediation:**
-Since immutable is a transitive dependency, investigate the dependency tree and either:
-1. Update the direct dependency that requires immutable
-2. Use package manager overrides/resolutions:
-
-```json
-// pnpm-lock.yaml or package.json
-"pnpm": {
-  "overrides": {
-    "immutable": ">=5.1.5"
-  }
-}
-```
-
-**References:**
-- Issue: #5318
-- Dependabot: https://github.com/mem0ai/mem0/security/dependabot/566
-- Advisory: https://github.com/immutable-js/immutable-js/security/advisories/GHSA-wf6x-7x77-mvgw
-
-### 2. CVE-2025-58754: Axios DoS via data: URI
-
-**Location:** Multiple locations (already fixed in most)  
-**Current Versions:** 1.15.2, 1.7.7 (SAFE)  
-**Required Version:** >= 1.12.0
-
-**Status:** ✅ RESOLVED - All axios instances are already at safe versions
-
-**Impact:**
-- Denial of Service through unbounded memory allocation
-- Process crash via malicious `data:` URIs
-- Bypasses `maxContentLength` / `maxBodyLength` limits
-
-**Verification:**
-```bash
-grep -r "axios" --include="package.json" | grep version
-# All instances show >= 1.12.0
-```
-
-**References:**
-- Issue: #5319
-- Dependabot: https://github.com/mem0ai/mem0/security/dependabot/567
-
-### 3. CVE-2026-32460: LangSmith SSRF & Credential Disclosure
-
-**Location:** Transitive dependency in `openclaw` and `mem0-ts`  
-**Current Versions:** 0.3.87, 0.5.10  
-**Required Version:** >= 0.6.0
-
-**Impact:**
-- Server-Side Request Forgery (SSRF) via untrusted prompts
-- Credential disclosure when pulling public prompts
-- Prompt injection and behavior manipulation
-
-**Remediation:**
-Since langsmith is a transitive dependency (likely from @langchain packages), investigate and either:
-1. Update the parent dependency (@langchain/core, etc.)
-2. Use package manager overrides:
-
-```json
-// pnpm-lock.yaml or package.json
-"pnpm": {
-  "overrides": {
-    "langsmith": ">=0.6.0"
-  }
-}
-```
-
-**Post-Upgrade Security Guidance:**
-After upgrading, pulling public prompts requires explicit opt-in:
-- Python: `dangerously_pull_public_prompt=True`
-- JS/TS: `dangerouslyPullPublicPrompt: true`
-
-**References:**
-- Issue: #5320
-- Dependabot: https://github.com/mem0ai/mem0/security/dependabot/920
-- Advisory: https://github.com/langchain-ai/langsmith-sdk/security/advisories/GHSA-3644-q5cj-c5c7
-
-## Recommended Actions

+
+**Major Release** — Migrated to Vercel AI SDK v6 (`LanguageModelV3` / `ProviderV3`) and Mem0 v3 API.
+
+**Breaking Changes:**
+- **AI SDK v6:** Upgraded from AI SDK v5 (`LanguageModelV2`) to v6 (`LanguageModelV3`). Users must upgrade `ai` to `^6.0.199` and all `@ai-sdk/*` provider packages to `^3.x` ([#4741](https://github.com/mem0ai/mem0/pull/4741))
+- **Mem0 v3 API:** Memory endpoints migrated from `/v1/memories/` and `/v2/memories/search/` to `/v3/memories/add/` and `/v3/memories/search/`. Entity IDs (`user_id`, `agent_id`, `run_id`) now go inside the `filters` object for search requests ([#4741](https://github.com/mem0ai/mem0/pull/4741))
+- **Graph memory removed:** All `enable_graph`, graph prompts, and relation-extraction code removed. Graph memory is now a project-level setting on the Platform ([#4741](https://github.com/mem0ai/mem0/pull/4741))
+- **Deprecated params removed:** `org_id`, `project_id`, `org_name`, `project_name`, `output_format`, `filter_memories`, `async_mode`, `enable_graph`, `version`, `api_version` removed from `Mem0ConfigSettings` ([#4741](https://github.com/mem0ai/mem0/pull/4741))
+
+**New Features:**
+- **V3 provider contract:** `specificationVersion: 'v3'`, `supportedUrls` property, V3 content array in `doGenerate`, V3 stream lifecycle events in `doStream` ([#4741](https://github.com/mem0ai/mem0/pull/4741))
+- **Mem0 source in responses:** Memories are attached as a `source` in `generateText`/`streamText` responses with `providerMetadata.mem0.memories` for programmatic access ([#4741](https://github.com/mem0ai/mem0/pull/4741))
+
+**Bug Fixes:**
+- **Async memory storage:** `addMemories` is now properly `await`ed — memories no longer silently fail to store ([#4741](https://github.com/mem0ai/mem0/pull/4741))
+- **Prompt mutation:** Prompt array is now cloned before injecting memory context, preventing side effects on the caller's array ([#4741](https://github.com/mem0ai/mem0/pull/4741))

+---
+
+Use [Neon](https://neon.com/) as a vector store in Mem0, powered by PostgreSQL and the
+[pgvector extension](https://neon.com/docs/extensions/pgvector).
+
+Neon is a serverless Postgres platform. Since Mem0 supports Postgres through the
+`pgvector` provider, Neon can be used with a standard Postgres connection string.
+
+## Usage
+
+<CodeGroup>
+```python Python
+import os
+
+from dotenv import load_dotenv
+from mem0 import Memory
+
+load_dotenv()
+
+config = {
+    "vector_store": {
+        "provider": "pgvector",
+        "config": {
+            "connection_string": os.environ["DATABASE_URL"],
+            "collection_name": "memories",
+            "embedding_model_dims": 1536,
+            "hnsw": True,
+        },
+    },
+}

+]
+m.add(messages, user_id="alice", metadata={"category": "movies"})
+
+results = m.search(
+    "What movies should I recommend?",
+    filters={"user_id": "alice"},
+)
+

+## SQL Migration
+
+You don't need to run any SQL migrations. Mem0 creates the collection table when it initializes the `pgvector` store.
+
+## Environment
+
+```env
+OPENAI_API_KEY=sk-xx...
+DATABASE_URL=postgresql://user:password@ep-example.us-east-2.aws.neon.tech/neondb?sslmode=require
+```

+| Parameter | Description | Default Value |
+| --- | --- | --- |
+| `connection_string` | Neon Postgres connection string. | Required |

+| `embedding_model_dims` | Embedding model dimensions. | `1536` |
+| `hnsw` | Enables HNSW indexing. | `False` |

+</Tabs>
+
+### Indexing
+
+The `pgvector` provider can create an HNSW index for faster vector search.
+
+- Set `hnsw` to `true` to enable a Hierarchical Navigable Small World index.
+- Leave `hnsw` as `false` if you want to create or manage indexes yourself.
+
+### Similarity Search
+
+The `pgvector` provider uses cosine similarity for vector search. Make sure your
+embedding dimensions match the configured `embedding_model_dims` value.
+
+### Best Practices
+
+1. **Index Selection**:
+   - Use `hnsw` for faster search performance when memory usage is not a constraint
+   - Manage indexes manually if you need a different pgvector index strategy
+
+2. **Connection String**:
+   - Always use environment variables or even better, a secret manager for sensitive information in the connection string
+   - Format: `postgresql://user:password@host:port/database`

 ## Overview
 
-1. Store and retrieve memories from Mem0 within Google ADK agents
+In this guide, we'll create a Google ADK agent that:
-2. Multi-agent workflows with shared memory across hierarchies
+1. Uses ADK's native `MemoryService` interface to connect Mem0
-3. Retrieve relevant memories from past conversations
+2. Automatically injects relevant memories using ADK's built-in `load_memory` tool
-4. Personalized responses based on user history
+3. Persists session history to Mem0 after each turn via an after-agent callback
+4. Shares memory seamlessly across multi-agent hierarchies
 
-## Prerequisites
+## Setup and Configuration
 
-Before setting up Mem0 with Google ADK, ensure you have:
+Install the necessary libraries:
 
-1. Installed the required packages:
 ```bash
 pip install google-adk mem0ai python-dotenv
 ```
 
-2. Valid API keys:
+Set up your API keys:
    - <a href="https://app.mem0.ai/dashboard/api-keys?utm_source=oss&utm_medium=integration-google-ai-adk" rel="nofollow">Mem0 API Key</a>
    - Google AI Studio API Key

 ## Multi-Agent Hierarchy with Shared Memory
 
-Create specialized agents in a hierarchy that share memory:
+Because `memory_service` is passed to the `Runner`, every agent in the hierarchy shares the same memory automatically. Only the root coordinator needs the auto-save callback — ADK fires it once when the full turn completes:

-
-        if user_input.lower() == 'quit':

 ```
 
 ## Key Features
 
-### 1. Memory-Enhanced Function Tools
+1. **Automatic Memory Injection**: ADK's built-in `load_memory` tool searches Mem0 at the start of each turn and injects relevant memories directly into the agent context — no prompt instructions needed.
-- **Function Tools**: Standard Python functions that can search and save memories
+2. **Automatic Session Saving**: The `save_session_to_memory` callback persists every completed turn to Mem0 without any manual calls.
-- **Tool Context**: Access to session state and memory through function parameters
+3. **Native ADK Integration**: `Mem0MemoryService` implements ADK's `BaseMemoryService` and integrates via the `Runner` — works natively across the entire agent hierarchy.
-- **Structured Returns**: Dictionary-based returns with status indicators for better LLM understanding
+4. **User Scoping**: `user_id` is passed automatically from the ADK session context, ensuring memories are always scoped to the correct user.
-
+5. **Multi-Agent Support**: A single `Mem0MemoryService` instance shared through the `Runner` gives all agents — coordinators and specialists — access to the same user memory.
-### 2. Multi-Agent Memory Sharing
-- **Agent-as-a-Tool**: Specialists can be called as tools while maintaining shared memory
-- **Hierarchical Delegation**: Coordinator agents route to specialists based on context
-- **Memory Categories**: Store interactions with metadata for better organization
-
-### 3. Flexible Memory Operations
-- **Search Capabilities**: Retrieve relevant memories through conversation history
-- **User Segmentation**: Organize memories by user ID
-- **Memory Management**: Built-in tools for saving and retrieving information
 
 ## Configuration Options
 
-Customize memory behavior and agent setup:
+### Using Vertex AI
+
+To use Google Cloud Vertex AI instead of AI Studio, set the following environment variables before creating agents:
 
 ```python
-# Configure memory search with filters
+import os
-# For Platform API, all filters including user_id go in filters object
-memories = mem0.search(
-    query="travel preferences",
-    filters={
-        "AND": [
-            {"user_id": "alice"},
-            {"categories": {"contains": "travel"}}
-        ]
-    },
-    top_k=5
-)
-
-# Configure agent with custom model settings
-agent = Agent(
-    name="custom_agent",
-    model="gemini-2.0-flash",  # or use LiteLLM for other models
-    instruction="Custom agent behavior",
-    tools=[memory_tools],
-    # Additional ADK configurations
-)
-
-# Use Google Cloud Vertex AI instead of AI Studio
 os.environ["GOOGLE_GENAI_USE_VERTEXAI"] = "True"
 os.environ["GOOGLE_CLOUD_PROJECT"] = "your-project-id"
 os.environ["GOOGLE_CLOUD_LOCATION"] = "us-central1"
 ```
 
+### Advanced Memory Filtering
+
+You can customize how memories are searched by modifying `Mem0MemoryService.search_memory`. For example, to filter by category:
+
+```python
+results = await asyncio.to_thread(
+    self._client.search,
+    query,
+    filters={
+        "AND": [
+            {"user_id": user_id},
+            {"app_id": app_name},
+            {"categories": {"contains": "travel"}}
+        ]
+    },
+    top_k=10,
+)
+```
+
+<Note>`InMemorySessionService` stores sessions in memory and is intended for prototyping. For production, use a persistent session service and clean up sessions when they are no longer needed.</Note>
+
+## Conclusion
+
+By implementing `Mem0MemoryService` as an ADK `BaseMemoryService`, you get persistent, user-scoped memory across single agents and complex multi-agent hierarchies with minimal code. Memory injection and session saving happen automatically, keeping your agent prompts clean and your token usage efficient.

+title: Pi Agent
+description: "Add persistent memory to Pi Agent with the Mem0 plugin semantic search, auto-capture, and dream consolidation."
+---
+
+Add persistent memory to [**Pi Agent**](https://pi.dev) with `@mem0/pi-agent-plugin`. Your agent forgets everything between sessions — this plugin fixes that by automatically capturing knowledge from conversations, storing it in Mem0's cloud memory layer, and retrieving relevant context before every response.
+
+## Overview
+
+The plugin provides:
+1. **Auto-capture** — Extracts durable facts from both user and assistant messages automatically
+2. **Semantic recall** — Retrieves relevant memories via the `mem0_memory` tool before each response
+3. **Dream consolidation** — Periodic maintenance: merges duplicates, resolves contradictions, prunes stale entries
+4. **Monorepo-aware scoping** — Uses git root for project detection, consistent across subdirectories
+5. **Confirmation dialogs** — Destructive commands ask before acting via Pi's built-in UI
+6. **8 skills + 8 commands** — Essential memory management from slash commands and agent-guided workflows
+
+## Prerequisites
+
+1. A Mem0 Platform account and API key:
+   - <a href="https://app.mem0.ai?utm_source=oss&utm_medium=integration-pi-agent" rel="nofollow">Sign up at app.mem0.ai</a>
+   - <a href="https://app.mem0.ai/dashboard/api-keys?utm_source=oss&utm_medium=integration-pi-agent" rel="nofollow">Get your API key</a> (starts with `m0-`)
+
+2. Pi Agent installed ([pi.dev](https://pi.dev))
+
+3. Your API key added to your shell profile:
+
+<CodeGroup>
+```bash zsh
+echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.zshrc
+source ~/.zshrc
+```
+
+```bash bash
+echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.bashrc
+source ~/.bashrc
+```
+</CodeGroup>
+
+## Installation
+
+```bash
+pi install npm:@mem0/pi-agent-plugin
+```
+
+That's it. The extension loads automatically on every Pi session. No config files needed — `MEM0_API_KEY` from your environment is picked up automatically.
+
+<Info>
+  Start a new Pi session and run `/mem0-status` to verify the connection. You should see your user ID, detected project, and memory count.
+</Info>
+
+### Optional Configuration
+
+For advanced settings, create `~/.pi/agent/mem0-config.json`:
+
+```json
+{
+  "apiKey": "m0-your-key-here",
+  "userId": "your-username",
+  "autoCapture": true,
+  "defaultScope": "project",
+  "dream": {
+    "enabled": true,
+    "auto": true,
+    "minHours": 24,
+    "minSessions": 5,
+    "minMemories": 20
+  }
+}
+```
+
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| `apiKey` | `string` | `$MEM0_API_KEY` | Mem0 API key. Environment variable takes precedence. |
+| `userId` | `string` | `$MEM0_USER_ID` or `"default"` | User identity for memory scoping |
+| `autoCapture` | `boolean` | `true` | Store facts from conversations automatically |
+| `defaultScope` | `string` | `"project"` | Default memory scope: `project`, `session`, or `global` |
+| `dream.enabled` | `boolean` | `true` | Enable dream consolidation |
+| `dream.auto` | `boolean` | `true` | Auto-trigger dreams when thresholds are met |
+| `dream.minHours` | `number` | `24` | Minimum hours between auto-dreams |
+| `dream.minSessions` | `number` | `5` | Minimum sessions before first auto-dream |
+| `dream.minMemories` | `number` | `20` | Minimum memories before auto-dream triggers |
+
+## What's Included
+
+| Component | Description |
+|-----------|-------------|
+| `mem0_memory` tool | Agent-callable tool for search, add, get_all, delete, delete_all |
+| 8 slash commands | Essential memory management from the command line |
+| 8 skills | Guide the agent on how to use each capability |
+| Auto-capture | Extracts and stores facts on every `agent_end` event |
+| System prompt | Appends memory policy to every agent turn |
+| Dream consolidation | Automated memory maintenance with session/time/count gates |
+
+## Agent Tool
+
+The `mem0_memory` tool is registered with Pi and callable by the agent during conversations:
+
+| Action | Required Params | Description |
+|--------|----------------|-------------|
+| `search` | `query` | Semantic search across memories |
+| `add` | `content` | Store a new memory |
+| `get_all` | — | List all memories in scope |
+| `delete` | `memory_id` | Delete a specific memory |
+| `delete_all` | — | Delete all memories in scope |
+
+All actions accept an optional `scope` parameter: `project` (default), `session`, or `global`.
+
+Tool output is truncated to 200 lines / 50KB to prevent context overflow.
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `/mem0-remember <text>` | Store a memory verbatim (no inference) |
+| `/mem0-forget <query>` | Search and delete memories (with confirmation dialog) |
+| `/mem0-search <query>` | Semantic search across memories |
+| `/mem0-tour [scope]` | Browse all memories grouped by category |
+| `/mem0-dream` | Consolidate — merge duplicates, prune stale, resolve contradictions |
+| `/mem0-pin <query>` | Pin a memory to protect from dream pruning (preserves memory ID) |
+| `/mem0-scope <scope>` | Change default scope for this session (project, session, global) |
+| `/mem0-status` | Connection health, identity, and memory count |
+
+## Memory Scopes
+
+Memories are scoped using Mem0's `user_id`, `app_id`, and `run_id` parameters:
+
+| Scope | Filters | Use Case |
+|-------|---------|----------|
+| `project` | user_id + app_id (git root) | **Default.** Project-specific knowledge — decisions, architecture, config |
+| `session` | user_id + app_id + run_id | Ephemeral context for the current session only |
+| `global` | user_id only | All memories across all your projects |
+
+The `app_id` is auto-detected from the git repository root (`git rev-parse --show-toplevel`), so all subdirectories within a monorepo share the same memory pool. Falls back to the working directory name for non-git directories. The `run_id` is derived from Pi's session file path.
+
+## Dream Consolidation
+
+### Confirmation Dialogs
+
+Destructive and mutating commands use Pi's built-in `ctx.ui.confirm()` dialog before acting:
+
+- `/mem0-forget` asks "Delete this memory?" before deleting a single match
+- `/mem0-pin` asks "Pin this memory?" before modifying it
+- Cancelling either operation is always safe — no changes are made
+
+### Pin
+
+`/mem0-pin` uses Mem0's `update()` API to prepend `[PINNED]` to the memory text. This preserves the original memory ID — no add+delete cycle that would lose history or change the UUID.
+
+### Dream Consolidation
+
+The plugin includes automated memory maintenance ("dream") that merges duplicates, resolves contradictions, and prunes stale entries. When enabled, dreams auto-trigger after enough sessions, time, and memories accumulate (configurable via `dream.*` settings). Run `/mem0-dream` to trigger consolidation manually at any time. Pinned memories (via `/mem0-pin`) are protected from pruning.
+
+## Example Workflow
+
+```text
+# Session 1
+You: I prefer dark mode and concise answers.
+# Mem0 auto-captures preferences
+
+# Session 2 (days later)
+You: What do you know about my preferences?
+# Pi retrieves stored memories — no re-explaining needed
+```
+
+## Troubleshooting
+
+- **"No API key found"** — Verify `MEM0_API_KEY` is set: `echo $MEM0_API_KEY`. If empty, add it to your shell profile (see Prerequisites)
+- **Extension not loading** — Check Pi startup output for errors. Run `pi -e ./src/entry.ts` from the plugin directory for verbose output
+- **Memories not capturing** — Verify `autoCapture` is `true` (default). Check `/mem0-status` for connection health
+- **Wrong project detected** — The plugin uses the git repository root as `app_id`. If not in a git repo, it falls back to the working directory name. Run `/mem0-status` to see the detected project
+- **Dream not triggering** — All three gates must pass (time, sessions, memories). Use `/mem0-dream` to force it manually

 ## Key Features
 
-- `createMem0()`: Initializes a new Mem0 provider instance.
+- `createMem0()`: Initializes a new Mem0 provider instance implementing `ProviderV3`.
-- `retrieveMemories()`: Retrieves memory context for prompts.
+- `retrieveMemories()`: Retrieves memory context for prompts as a formatted system prompt string.
 - `getMemories()`: Get memories from your profile in array format.
 - `addMemories()`: Adds user memories to enhance contextual responses.
 
+## Migrating from v2.x
+
+If you're upgrading from `@mem0/vercel-ai-provider` v2.x:
+
+1. **Upgrade AI SDK**: `npm install ai@^6` and update all `@ai-sdk/*` provider packages to `^3.x`
+2. **Remove deprecated params**: Remove `org_id`, `project_id`, `output_format`, `filter_memories`, `async_mode`, `enable_graph` from your config
+3. **Remove graph memory**: All graph-related options (`enable_graph`, graph prompts) have been removed. Graph memory is now a project-level setting on the Mem0 Platform
+4. **Update imports**: `LanguageModelV2Prompt` is now `LanguageModelV3Prompt` if you import types directly
+
 ## Best Practices
 
 1. **User Identification**: Use a unique `user_id` for consistent memory retrieval.
 2. **Memory Cleanup**: Regularly clean up unused memory data.
+3. **Sources**: Access `result.sources` to inspect which memories influenced the response.
 
     > **Note**: We also have support for `agent_id`, `app_id`, and `run_id`. Refer [Docs](/api-reference/memory/add-memories).

+description: "Migrate your self-hosted Mem0 server from the archived ankane/pgvector image to the official pgvector/pgvector image."
+icon: "arrow-right"
+iconType: "solid"
+---
+
+## Overview
+
+The self-hosted Mem0 server has upgraded its PostgreSQL Docker image:
+
+| | Before | After |
+| --- | --- | --- |
+| Docker image | `ankane/pgvector:v0.5.1` | `pgvector/pgvector:pg17` |
+| PostgreSQL | 15 | 17 |
+| pgvector | 0.5.1 | 0.8.0 |
+| Credentials | Hardcoded `postgres` / `postgres` | Set via `POSTGRES_USER` / `POSTGRES_PASSWORD` env vars |
+
+<Warning>
+The `ankane/pgvector` image is **archived and no longer maintained**. The new `pgvector/pgvector` image is the official distribution maintained by the pgvector project.
+</Warning>
+
+<Info>
+**Should you migrate?**
+- You are running the Mem0 server via `docker-compose.yaml` in the `server/` directory.
+- You want to stay on a maintained, actively-patched PostgreSQL + pgvector image.
+- You want pgvector 0.8.0 features (improved HNSW performance, parallel index builds).
+</Info>
+
+## Fresh Installs
+
+No migration is needed. Copy the example env file, set your password, and start the stack:
+
+```bash
+cd server
+cp .env.example .env
+# Edit .env — set POSTGRES_PASSWORD (required) and OPENAI_API_KEY at minimum
+make up
+```
+
+## Migrating an Existing Install
+
+PostgreSQL 17 cannot read data files created by PostgreSQL 15 directly. You need to export your data from the old container and import it into the new one.
+
+### 1. Back Up Your Data
+
+With the **old** stack still running:
+
+```bash
+cd server
+docker compose exec -T postgres pg_dumpall -U postgres > mem0_backup.sql
+```
+
+Verify the dump is non-empty:
+
+```bash
+ls -lh mem0_backup.sql
+```
+
+<Warning>
+Do not skip this step. The next step permanently deletes your Postgres data volume.
+</Warning>
+
+### 2. Stop the Old Stack and Remove the Volume
+
+```bash
+docker compose down
+docker compose down -v
+```
+
+### 3. Update Your `.env`
+
+Postgres credentials are no longer hardcoded in `docker-compose.yaml`. Add them to your `.env`:
+
+```bash
+POSTGRES_HOST=postgres
+POSTGRES_PORT=5432
+POSTGRES_DB=postgres
+POSTGRES_USER=postgres
+POSTGRES_PASSWORD=<your-password>    # required — compose will refuse to start without it
+POSTGRES_COLLECTION_NAME=memories
+```
+
+<Info>
+`POSTGRES_PASSWORD` is **required** — `docker compose up` will refuse to start without it. If you previously relied on the hardcoded default, set `POSTGRES_PASSWORD=postgres`.
+</Info>
+
+### 4. Start Only Postgres
+
+Start **only** the Postgres container first — do **not** start the mem0 API yet.
+The API runs `alembic upgrade head` on startup, which creates empty tables that
+would conflict with the restore.
+
+```bash
+docker compose up -d postgres
+```
+
+Wait for Postgres to become healthy:
+
+```bash
+docker compose exec -T postgres pg_isready -q && echo "ready" || echo "not ready"
+```
+
+### 5. Restore Your Data
+
+```bash
+docker compose exec -T postgres psql -U postgres < mem0_backup.sql
+```
+
+You may see notices like `role "postgres" already exists` — these are safe to ignore.
+
+<Warning>
+You must restore **before** starting the mem0 API container. The API runs
+database migrations on startup which create empty tables — restoring after
+that would fail with duplicate-key errors and lose your API keys and settings.
+</Warning>
+
+### 6. Start the API
+
+Now start the mem0 API container. Alembic will detect the existing tables and
+only apply any new migrations:
+
+```bash
+docker compose up -d mem0
+```
+
+### 7. Verify
+
+```bash
+# Check service health
+cd server && make health
+
+# Confirm memories are accessible
+curl -s http://localhost:8888/memories?user_id=<your-user-id> \
+  -H "X-API-Key: <your-api-key>"
+```
+
+## Rollback
+
+If something goes wrong, revert the image tag in `docker-compose.yaml`:
+
+```yaml
+postgres:
+    image: ankane/pgvector:v0.5.1
+```
+
+Then destroy the new volume, start the old image, and restore from your backup:
+
+```bash
+docker compose down -v
+docker compose up -d --build
+docker compose exec -T postgres psql -U postgres < mem0_backup.sql
+```

+# Changelog
+
+All notable changes to the `@mem0/opencode-plugin` will be documented in this file.
+
+## 0.1.3 — File-context injection, session summaries & activity timeline
+
+### Added
+
+- **File-context injection (`tool.execute.before` / Read):** Before the agent reads a file, the plugin searches mem0 for memories referencing that file path and injects prior work as system context. Gates on file size (>= 1,500 bytes). Gives the agent "I've worked on this file before" awareness automatically.
+- **Stop hook session summary (`experimental.session.compacting`):** Enhanced session compaction to store a structured `session_summary` memory with `infer=True`, letting the mem0 backend AI extract key facts (request, decisions, learnings, next steps). Previously only stored a raw stats string.
+- **SessionStart activity timeline:** The initial memory loading now formats recent memories with type icons (⚖️ decision, 🔴 bug_fix, 🔵 task_learning, etc.) and relative age indicators (2h ago, 1d ago) instead of bare text. Provides a visual "Recent Activity" timeline on first message.
+
+### Changed
+
+- **`experimental.session.compacting` handler:** Now stores `metadata.type=session_summary` with `metadata.source=opencode-stop` instead of `metadata.type=session_state` with `metadata.source=pre-compaction`. Includes a structured prompt that instructs mem0's AI to extract request, decisions, learnings, and next steps.
+- **Initial context formatting:** Memories shown on first message now include type icons and age labels for quick scanning.
+
+## 0.1.2 — Automatic coding categories & global search
+
+### Added
+
+- **Auto-configured coding categories:** The plugin now automatically sets up 17 coding categories (e.g. `architecture_decisions`, `api_design`, `security`, `debugging_notes`) on the Mem0 project at startup. Runs in the background on every session start via `autoSetupCategories()`, is fully idempotent, and never blocks initialization. Uses SHA-256 fingerprints of the category list and API key — stored in `~/.mem0/categories_setup.json` — to skip redundant API calls on subsequent sessions.
+- **Global search mode (`global_search` setting):** New `global_search` toggle in `~/.mem0/settings.json` (default: `false`). When enabled, all `search_memories` and `get_memories` calls use `{"OR": [{"user_id": "*"}]}` instead of the per-user per-project `AND` filter — returning all memories across all users and all `app_id` scopes. Writes (`add_memory`) still tag with the current `user_id` and `app_id`. Applies to all plugin search paths: initial load, per-message recall, resume detection, error-pattern lookup, and compaction context.
+- **`/mem0:switch-project --global` / `--no-global`:** Enables or disables global search via the switch-project skill. Persists to `~/.mem0/settings.json`. No manual config editing needed.
+- **`MEM0_GLOBAL_SEARCH` environment variable:** Exported to child shells via the `shell.env` hook (`"true"` or `"false"`).
+
+### Changed
+
+- **Search filters are now dynamic:** All search paths throughout the plugin construct filters based on the `global_search` setting instead of always using `AND [user_id, app_id]`.
+- **Resume-context searches broadened:** Resume and error-pattern searches no longer include `metadata.type` sub-filters (`session_state`, `decision`, `anti_pattern`, `bug_fix`), broadening recall.
+- **System context message updated:** Informs the model when global search is active (`"Global search is ON — searches return all memories across all users and projects. Writes still use user_id=..., app_id=..."`).
+- **`/mem0:onboard` Step 5 is no longer interactive:** Removed the manual category installation prompt. Categories now configure automatically in the background; the onboarding step only verifies status and stores a fallback `project_profile` memory if the background run hasn't finished yet.
+- **`/mem0:switch-project` skill expanded:** Description and execution updated to document the `--global` and `--no-global` flags alongside the existing project-name argument.
+
+## 0.1.1
+
+- CI/CD publish flow test (`#5288`).
+- Fixed tsconfig, added `publishConfig` and bun lockfile (`#5273`).
+- Renamed package to `@mem0/opencode-plugin` (`#5272`).
+- Added plugin array to bundled `opencode.json` (`#5271`).
+
+## 0.1.0 — Initial release
+
+- **OpenCode plugin** (`@mem0/opencode-plugin` on npm): Pure TypeScript plugin using the `mem0ai` TS SDK — no Python, no shell scripts. Hooks into all 6 OpenCode events (`chat.message`, `tool.execute.before`, `tool.execute.after`, `experimental.chat.system.transform`, `experimental.session.compacting`, `shell.env`). Features: session start memory loading, per-prompt semantic search, error pattern detection with memory lookup, resume/remember intent detection, auto-capture every 3rd message, periodic save nudges, full metadata defaults injection (confidence, source, type, session_id, files, branch), identity injection for search/get/delete filters, type-filtered error pre-fetch (anti_pattern + bug_fix), pre-compaction memory capture, MEMORY.md write blocking, and secret redaction.
+- **16 OpenCode-native skills** bundled in `opencode-skills/`: `context-loader`, `dream`, `export`, `forget`, `health`, `import`, `list-projects`, `mem0` (SDK reference), `memory-reviewer`, `onboard`, `peek`, `pin`, `remember`, `stats`, `switch-project`, `tour`. All skills are pure MCP-tool-based — no Python scripts, no shell scripts, no Claude Code dependencies.
+- **Auto-install skills and commands (`installSkills()`):** On plugin load, copies all 16 skills to `.opencode/skills/` and creates command wrapper files in `.opencode/commands/` so they appear in the OpenCode `/` palette.
+- **CLI installer (`cli.ts`):** `bunx @mem0/opencode-plugin install` auto-configures plugin and MCP server in `~/.config/opencode/opencode.json`.

 All notable changes to the Mem0 plugin will be documented in this file.
 
+## 0.2.9 — File-context injection, session summaries & activity timeline
+
+### Added
+
+- **File-context injection (`PreToolUse/Read` hook):** Before Claude reads a file, the new `on_file_read.sh` hook searches mem0 for memories that reference that file path and injects a compact timeline of prior work as `additionalContext`. Gives Claude "I've seen this file before and here's what I remember" context automatically. Gates on file size (>= 1,500 bytes), 5-second hard timeout, silent skip on any failure. Applies to Claude Code, Codex, and Cursor (`on_file_read_cursor.sh`).
+- **Stop hook session summary (`on_stop.sh`):** On session end, parses the transcript JSONL, extracts the last assistant message and files touched, builds a structured prompt, and stores it via the mem0 API with `infer=True` — letting the platform's backend AI extract structured facts (request, decisions, learnings, next steps). Memories are stored as `metadata.type=session_summary` with 90-day expiry. Guards: skips subagent sessions (`agent_id` present), dedup via marker file, always exits 0. Applies to Claude Code, Codex, and Cursor (`on_stop_cursor.sh`).
+- **SessionStart activity timeline (`session_timeline.py`):** On startup (when project has existing memories), fetches the 10 most recent memories and renders a compact timeline with type icons, age indicators, and short text below the existing banner. Shows recent decisions, bug fixes, and session summaries at a glance. 5-second timeout — if the API is slow, the timeline silently skips while the banner still displays.
+- **`scripts/file_context.py`:** Core Python module for file-context injection. Searches mem0 cloud API with both relative and absolute file paths, deduplicates results, formats as compact timeline with type icons and memory age.
+- **`scripts/capture_session_summary.py`:** Core Python module for Stop hook. Reads transcript JSONL (tail 3,000 lines), extracts last assistant message, extracts file paths from tool_input fields, strips system tags and `<private>` blocks, stores via mem0 API.
+- **`scripts/session_timeline.py`:** Core Python module for SessionStart timeline. Fetches recent memories from mem0 API, formats with type icons, relative age, and short text.
+
+### Changed
+
+- **`on_session_start.sh`:** On startup (when memories > 0), calls `session_timeline.py` to inject a compact recent activity timeline below the existing banner and rubric instructions.
+- **`hooks/hooks.json`:** Added `PreToolUse` matcher for `Read` (5s timeout) and `Stop` hook (30s timeout).
+- **`hooks/codex-hooks.json`:** Added `PreToolUse` matcher for `Read` (5s timeout) and `Stop` hook (30s timeout).
+- **`hooks/cursor-hooks.json`:** Added `preToolUse` matcher for `Read` (5s timeout) and `stop` hook (30s timeout).
+
 ## 0.2.8 — Automatic coding categories & global search
 
 ### Added
 
-- **Global search mode (`global_search` setting):** New `global_search` toggle in `~/.mem0/settings.json` (default: `false`). When enabled, `search_memories` and `get_memories` calls use `{"OR": [{"user_id": "*"}]}` instead of the per-user per-project `AND` filter — returning all memories across all users and all `app_id` scopes in the platform project. Writes (`add_memory`) still tag with the current `user_id` and `app_id`. Solves the team-shared-memory use case where multiple team members need access to all memories regardless of which repo or user created them. Works on Claude Code, Cursor, and Codex (not OpenCode, which has its own TypeScript identity logic).

 - **`/mem0:switch-project --global` / `--no-global`:** Enables or disables global search via the switch-project skill. Persists to `~/.mem0/settings.json`. No manual config editing needed.
 - **Session banner scope indicator:** Banner shows `scope=global` when global search is active instead of `project=<app_id>`.
 - **Global-aware memory count:** Session start memory count query uses the global filter when `global_search` is enabled.
@@ -20,17 +38,10 @@ All notable changes to the Mem0 plugin will be documented in this file.
 - **`/mem0:onboard` Step 5 is no longer interactive:** Removed the `Install coding categories? [Y/n]` prompt. Categories now configure automatically in the background; the onboarding step only verifies status and applies them if the background run hasn't finished yet — mirroring how Step 4 (project-file import) already works.
 - **Session-start "new project" hint** now notes that coding categories install automatically in the background.
 
-## 0.1.0 — OpenCode & Antigravity
+## 0.1.0 — Antigravity
 
 ### Added
 
-- **OpenCode plugin** (`@mem0/opencode-plugin` on npm): Pure TypeScript plugin using the `mem0ai` TS SDK — no Python, no shell scripts. Hooks into all 6 OpenCode events (`chat.message`, `tool.execute.before`, `tool.execute.after`, `experimental.chat.system.transform`, `experimental.session.compacting`, `shell.env`). Features: session start memory loading, per-prompt semantic search, error pattern detection with memory lookup, resume/remember intent detection, auto-capture every 3rd message, periodic save nudges, full metadata defaults injection (confidence, source, type, session_id, files, branch), identity injection for search/get/delete filters, type-filtered error pre-fetch (anti_pattern + bug_fix), pre-compaction memory capture, MEMORY.md write blocking, and secret redaction.
-- **16 OpenCode-native skills** bundled in `opencode-skills/`: `context-loader`, `dream`, `export`, `forget`, `health`, `import`, `list-projects`, `mem0` (SDK reference), `memory-reviewer`, `onboard`, `peek`, `pin`, `remember`, `stats`, `switch-project`, `tour`. All skills are pure MCP-tool-based — no Python scripts, no shell scripts, no Claude Code dependencies.
-- **Auto-install skills and commands (`installSkills()`):** On plugin load, copies all 16 skills to `.opencode/skills/` and creates command wrapper files in `.opencode/commands/` so they appear in the OpenCode `/` palette. No manual setup needed.
-- **`extractUserText()` handler:** Robust text extraction from OpenCode response shapes — handles `parts[]` array, `content[]` array, `message.content`, and plain string responses.
-- **Identity resolution:** `getUserId()` uses `os.userInfo().username` (matching Claude Code's `${USER}` convention) with `MEM0_USER_ID` env override. `getProjectId()` uses git remote with `MEM0_APP_ID` env override.
-- **Context injection via `experimental.chat.system.transform`:** All memory context (session start memories, per-prompt search results, error-related memories, compaction context) injected as system context.
-- **CLI installer (`cli.ts`):** `bunx @mem0/opencode-plugin install` auto-configures plugin and MCP server in `~/.config/opencode/opencode.json`.
 - **Antigravity plugin** (`.antigravity/`): Restructured to follow the same shared-infrastructure pattern as Claude Code, Cursor, and Codex. Self-contained plugin directory with `plugin.json`, `mcp_config.json`, `hooks/hooks.json` (own file), `scripts/` (symlink → `../scripts/`), and `skills/` (symlink → `../skills/`). Installable via `agy plugin install .antigravity` or `npx degit mem0ai/mem0/mem0-plugin/.antigravity ~/.gemini/config/plugins/mem0`. Uses `contextFileName: "AGENTS.md"` per Antigravity convention.
 - **Codex hooks parity:** Added missing `PreToolUse` Write/Edit/MultiEdit block and `PreCompact` hook to Codex hooks config, bringing it to full parity with Claude Code.

+# Changelog
+
+## 0.1.1 (2026-06-10)
+
+Maintenance release — no functional changes.
+
+### Chores
+
+- Version bump to validate the new release pipeline (`pi-agent-plugin-checks.yml` / `pi-agent-plugin-cd.yml`)
+
+## 0.1.0 (2026-06-09)
+
+Initial release of `@mem0/pi-agent-plugin` — persistent semantic memory for Pi Agent.
+
+### Features
+
+- **Extension entry point** — registers `mem0_memory` tool, 8 slash commands, and auto-capture hooks
+- **Agent tool** (`mem0_memory`) — search, add, get_all, delete, delete_all with scoped filters
+- **Auto-capture** — extracts and stores memories from both user and assistant messages on `agent_end`
+- **Dream consolidation** — automated memory maintenance: merge duplicates, resolve contradictions, prune stale entries. Gated by session count, time elapsed, and memory count thresholds
+- **System prompt injection** — appends `MEMORY_POLICY` to every agent turn via `before_agent_start`
+- **Monorepo-aware project scoping** — uses `git rev-parse --show-toplevel` for consistent app_id across subdirectories
+- **3 memory scopes** — project (default), session, global
+- **10 memory categories** — identity, preferences, goals, projects, decisions, technical, relationships, routines, lessons, work
+- **8 skills** — context-loader, remember, search, forget, dream, tour, pin, status
+- **Confirmation dialogs** — `/mem0-forget` and `/mem0-pin` ask for confirmation before destructive or mutating actions via `ctx.ui.confirm()`
+- **Pin preserves memory ID** — `/mem0-pin` uses `mem0.update()` instead of add+delete, keeping the original UUID
+- **Full memory IDs** — all displayed memory references show the complete UUID, not truncated short IDs
+- **Dream gate optimization** — `dreamChecked` flag prevents repeated `getAll` API calls when the memory gate fails
+- **Output truncation** — tool results capped at 200 lines / 50KB per Pi docs
+- **Signal cancellation** — all tool actions respect `AbortSignal`
+- **Session shutdown cleanup** — releases dream lock on `session_shutdown`
+- **PostHog telemetry** — batched event queue with PII-safe error payloads
+
+### Commands
+
+| Command | Description |
+|---------|-------------|
+| `/mem0-remember` | Store a memory verbatim (no inference) |
+| `/mem0-forget` | Search and delete memories (with confirmation) |
+| `/mem0-search` | Semantic search across memories |
+| `/mem0-tour` | Browse all memories by category |

+### Hooks
+
+| Hook | Purpose |
+|------|---------|

+| `before_agent_start` | Inject memory policy into system prompt, auto-trigger dream if gates pass |
+| `agent_end` | Auto-capture conversation memories, check dream completion |
+| `session_shutdown` | Release dream lock, flush telemetry |

+# @mem0/pi-agent-plugin
+
+Persistent semantic memory for [Pi Agent](https://pi.dev), powered by [Mem0](https://mem0.ai).
+
+This extension gives Pi Agent long-term memory that persists across sessions, projects, and devices. Memories are automatically captured from conversations and can be searched, managed, and consolidated through slash commands and an agent-accessible tool.
+
+## Features
+
+- **Automatic memory capture** — learns from every conversation (both user and assistant messages)
+- **Semantic search** — find memories by meaning, not just keywords
+- **Scoped memory** — project, session, or global scope
+- **Monorepo-aware** — uses git root for project detection, consistent app_id across subdirectories
+- **Dream consolidation** — merges duplicates, resolves contradictions, prunes stale entries
+- **Confirmation dialogs** — destructive commands ask before acting
+- **8 slash commands** — essential memory management from the command line
+- **Agent tool** — `mem0_memory` tool lets the agent search and store memories autonomously
+
+## Setup
+
+### 1. Get an API key
+
+Sign up at [app.mem0.ai](https://app.mem0.ai/dashboard/api-keys) and copy your API key.
+
+### 2. Install
+
+```bash
+pi install npm:@mem0/pi-agent-plugin
+```
+
+### 3. Configure
+
+Set the API key as an environment variable:
+
+```bash
+export MEM0_API_KEY="m0-your-key-here"
+```
+
+Or create a config file at `~/.pi/agent/mem0-config.json`:
+
+```json
+{
+  "apiKey": "m0-your-key-here",
+  "userId": "your-username",
+  "autoCapture": true,
+  "defaultScope": "project",
+  "dream": {
+    "enabled": true,
+    "auto": true,
+    "minHours": 24,
+    "minSessions": 5,
+    "minMemories": 20
+  }
+}
+```
+
+Environment variables (`MEM0_API_KEY`, `MEM0_USER_ID`) override the config file.
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `/mem0-remember <text>` | Store a memory verbatim (no inference) |
+| `/mem0-forget <query>` | Search and delete memories (with confirmation) |
+| `/mem0-search <query>` | Semantic search across memories |
+| `/mem0-tour [scope]` | Browse all memories grouped by category |
+| `/mem0-dream` | Consolidate — merge duplicates, prune stale, resolve contradictions |
+| `/mem0-pin <query>` | Pin a memory to protect from dream pruning (preserves ID) |
+| `/mem0-scope <scope>` | Change default scope for this session |
+| `/mem0-status` | Connection health, identity, and memory count |
+
+## Skills
+
+The plugin includes 8 skills that guide the agent on how to use each capability:
+
+| Skill | Purpose |
+|-------|---------|
+| `context-loader` | Pre-fetch relevant memories at session start |
+| `remember` | Store facts with category classification |
+| `search` | Quick semantic search with compact results |
+| `forget` | Delete memories with confirmation |
+| `dream` | Memory consolidation workflow |
+| `tour` | Full memory walkthrough by category |
+| `pin` | Protect critical memories from pruning |
+| `status` | Health check and diagnostics |
+
+## Memory Scopes
+
+| Scope | Filters | Use case |
+|-------|---------|----------|
+| `project` | user + app_id (git root) | Default. Project-specific knowledge |
+| `session` | user + app_id + run_id | Ephemeral, session-only context |
+| `global` | user only | All memories across all your projects |
+
+Project scoping uses `git rev-parse --show-toplevel` to detect the repository root, so all subdirectories within a monorepo share the same memory pool.
+
+## Memory Categories
+
+Memories are automatically classified into 10 general-purpose categories:
+
+| Category | Description |
+|----------|-------------|
+| `identity` | Personal details, background, self-descriptions |
+| `preferences` | Likes, dislikes, habits, preferred approaches |
+| `goals` | Objectives, aspirations, targets |
+| `projects` | Ongoing work, initiatives, areas of focus |
+| `decisions` | Choices made, rationale, trade-offs |
+| `technical` | Technical knowledge, tools, configurations |
+| `relationships` | People, teams, organizations |
+| `routines` | Recurring patterns, workflows, schedules |
+| `lessons` | Insights learned, mistakes to avoid |
+| `work` | Professional context, role, responsibilities |

+description: Searches and injects relevant memories into context before starting work on a task or topic. Use when beginning a new task, switching context, or when past decisions, preferences, or knowledge need to be loaded.
+---
+
+# Context Loader
+
+Pre-fetches relevant memories to prime context before working on a task or topic.
+
+## When to use
+
+- Session start (auto-triggered by the extension's `before_agent_start` event)
+- User starts work on a specific topic or area
+- User says "what do we know about X" or "context for X"
+
+## Steps
+
+1. **Extract topics** from current message/task. Identify: subject areas, people mentioned, project names, goal references.
+
+2. **Run 2-4 parallel searches** using `mem0_memory` tool with `action="search"` and different query angles:
+
+   | Query angle | Purpose |
+   |---|---|
+   | Topic/subject name | Relevant decisions and preferences |
+   | People mentioned | Relationship context |
+   | Project/goal references | Progress and background |
+   | Broad context | Catch-all for anything relevant |
+
+3. **Deduplicate** results by memory ID across all search responses.
+
+4. **Output compact context block** (max 10 memories):
+
+```
+context-loader: loaded <N> memories for "<task summary>"
+  - [decisions] <content> [mem0:<short_id>]
+  - [preferences] <content> [mem0:<short_id>]
+  - [lessons] <content> [mem0:<short_id>]
+```
+
+5. If **zero results**: output nothing. Don't announce empty context.
+
+## Constraints
+
+- **Read-only** — never modify or delete memories
+- **Max 10 memories** returned (most relevant only)
+- **Silent on empty** — only surfaces findings if relevant context exists
+- Skip memories already visible in current session context

+description: Consolidates stored memories by merging duplicates, resolving contradictions, and pruning stale entries. Use when memory count is high, search results feel noisy or repetitive, or periodic cleanup is needed to maintain memory quality.
+---
+
+# Dream — Memory Consolidation
+
+This skill performs a memory consolidation pass: it fetches all memories, identifies near-duplicates, flags contradictions, and prunes stale entries. All proposed changes are shown as a diff for user approval before anything is modified.
+
+**IMPORTANT: Execute steps strictly in order (1 -> 2 -> 3 -> 4 -> 5). Each step depends on the previous one. Do NOT run steps in parallel or skip ahead.**
+
+## Step 1: Fetch ALL Memories
+
+Use `mem0_memory` tool with `action="get_all"` to retrieve every memory.
+
+If zero memories are found, print:
+
+```
+No memories found. Nothing to consolidate.
+```
+
+...and stop.
+
+## Step 2: Analyze — Find Issues
+
+Work entirely in-memory; do not modify anything yet.
+
+Group memories by category. For each group, identify the following:
+
+### 2a. Near-duplicate pairs (merge candidates)
+
+Two memories are near-duplicates when they express the same fact but phrased differently (e.g., "Prefers morning meetings" and "Likes scheduling meetings early").
+
+Heuristics — two memories are near-duplicates if **all** of these hold:
+- If >60% of significant nouns/keywords overlap, treat as near-duplicate.
+- Same category.
+- Neither memory is pinned (content does not start with `[PINNED]`).
+
+For each qualifying pair, draft a merged version that is more complete than either original.
+
+### 2b. Contradictions
+
+Two memories contradict when they assert opposing facts about the same topic (e.g., "Prefers cats" vs. "Allergic to cats, prefers dogs").
+
+Identify the likely winner: the more recent memory wins. Store both IDs and their content for user review.
+
+### 2c. Prune candidates
+
+A memory is a prune candidate when **any** of the following is true:
+
+1. It is older than 180 days AND has not been accessed recently.
+2. Its content is extremely vague (fewer than 5 meaningful words).
+
+**Always skip memories where content starts with `[PINNED]`**, regardless of age.
+
+## Step 3: Print Diff Report
+
+Print a structured diff before making any changes:
+
+```
+## dream — consolidation report
+
+Merges (<N>):
+  [mem0:<id1>] + [mem0:<id2>] -> "<merged content, 100 chars>"
+
+Conflicts (<N>):
+  [mem0:<idA>] vs [mem0:<idB>] — "<topic>" [A/B/skip]
+
+Prune (<N>):
+  [mem0:<id>] — <category>, <age>d old
+
+Proposed: <N> merges, <N> prunes, <N> conflicts. Apply? [Y/n]
+```
+
+If there are zero total proposals, print:
+
+```
+Dream complete. No duplicate, contradictory, or stale memories found.
+```
+
+...and stop.
+
+## Step 4: Wait for User Input and Apply
+
+### 4a. Contradictions
+
+For each conflict pair, wait for the user to choose A, B, or skip.
+
+### 4b. Final confirmation
+
+After all conflict resolutions are collected, prompt: `Apply? [Y/n]`
+
+If the user declines, print `Cancelled. No changes made.` and stop.
+
+If confirmed, apply all changes:
+
+**Merges:** Delete both originals, add the merged version using `mem0_memory` with `action="add"`.
+
+**Contradictions (resolved):** Delete the loser using `mem0_memory` with `action="delete"`.
+
+**Prunes:** Delete each using `mem0_memory` with `action="delete"`.
+
+## Step 5: Print Summary
+
+```
+Dream complete — merged: <N>, pruned: <N>, conflicts resolved: <N>, skipped: <N>
+```
+
+## Auto mode
+
+When invoked with `--auto` (e.g., `/mem0-dream --auto`), run non-interactively:
+
+- **Merges**: applied automatically.
+- **Prunes**: applied automatically.
+- **Contradictions**: skipped — they require human judgment.
+
+Print a compact summary:
+```
+[mem0-dream --auto] merged=<N> pruned=<N> conflicts_skipped=<N>
+```

+description: Deletes memories by search query or memory ID with confirmation before removal. Use when removing outdated information, incorrect memories, sensitive data, or cleaning up after experiments.
+---
+
+# Forget
+
+Delete specific memories from Mem0.
+
+## Execution
+
+### Step 1: Parse input
+
+The user provides either:
+- A search query: `/mem0-forget travel plans`
+- A memory ID: `/mem0-forget <memory_id>`
+
+If no argument, ask: "What should I forget? Provide a search query or memory ID."
+
+### Step 2: Find memories
+
+**If memory ID provided** (looks like a UUID or hex string):
+- Use `mem0_memory` tool with `action="search"` and the ID as query, or look it up directly.
+- Show: `Found: "<memory content first 120 chars>" (created <date>)`
+
+**If search query provided:**
+- Use `mem0_memory` tool with `action="search"`, `query=<user's query>`.
+- Show numbered list:
+  ```
+  Found <N> memories matching "<query>":
+  1. <content, 120 chars> [<category>] [ID: <short_id>]
+  2. ...
+  ```
+
+### Step 3: Confirm
+
+Ask: "Delete which memories? Enter numbers (e.g., 1,3,5), 'all', or 'cancel'."
+
+For a single memory ID, ask: "Delete this memory? [y/N]"
+
+**Never delete without confirmation.** This is destructive.
+
+### Step 4: Delete
+
+For each confirmed memory, use `mem0_memory` tool with `action="delete"` and the memory ID.
+
+### Step 5: Report
+
+```
+Deleted <N> memories.
+```
+
+If any deletions failed, report which ones and why.
